Some Apple product owners have reported that iOS 7.1 is causing
the battery life inside of Apple's smartphone to drop
significantly.

Reports of poor battery life have surfaced on Twitter and Apple's
own support forums just days after iOS 7.1's public launch.

It's not just talk, though.

Ars Technica's Andrew Cunningham
tested the battery life across a host of Apple products,
including the iPhone 5s, 5, 4s, iPad mini and fourth-generation
iPad, finding that some devices showed shorter battery life
running on iOS 7.1 compared to iOS 7.

In most cases, Apple devices only showed a slight drop in battery
life during Ars Technica's Wi-Fi browsing test. For the iPhone
5s, the difference was only 20 minutes according to Cunningham's
review.

It's also worth noting that battery life varies for every user
depending on a variety of factors, including your phone or iPad's
screen brightness settings and how old the device is.

Here are a few of the complaints we've seen from Apple users so
far, which includes iLouge's Jeremy Horwitz.

Bad news: after five months of testing, iOS 7.1 has an iPhone
battery-killing bug. Good news: iOS 8 is only 6 short months
away. Maybe 7.
